NEET BIOLOGY

Detailed explanation-1: -If there is excess water loss from plant during transpiration, than is available in soil, the leaf cells lose turgidity and leaves droop down. This is called as wilting of plant. Thus, excessive transpiration causes plants to wilt.

Detailed explanation-2: -Excessive transpiration results in the wilting of the leaves.

Detailed explanation-3: -Wilting can be caused by drought or waterlogged soil Plants wilt when roots are unable to supply sufficient moisture to the stems and leaves. Wilting for short periods of time does not harm plants. Sometimes a plant wilts on a hot day because moisture is evaporating from the leaves faster than the roots can take it up.

Detailed explanation-4: -In such cases, the rate of transpiration during midday exceeds the rate of absorption of water by the roots. The cells, therefore, lose turgidity. So, excessive transpiration results in wilting of the leaves.

Detailed explanation-5: -Stomatal closure impacts the rate of photosynthesis when the water supply is constrained. When there is a water shortage, the stomata close, reducing the amount of carbon dioxide available. Water stress also causes leaves to wilt, which lowers the metabolic activity that leaves perform.
